I need help, I took a break from playing the TLD mod for a week or so, and now every time I try to launch the game it asks for the product key. I enter the key and it gives me the same pop up again, asking for the same product key. I can launch the vanilla game just fine, but I get thrown out of the mod saying I have to enter the key to continue playing.
Can someone please help me, this started to be my favourite game and now I can't play it anymore!
